Bootstrapping line defects with global symmetry
Aleix Gimenez-Grau, Edoardo Lauria, Pedro Liendo +1
We use the numerical bootstrap to study conformal line defects with global symmetry. Our results are very general and capture in particular conformal line defects originatin…
On the hydrodynamics of (2 + 1)-dimensional strongly coupled relativistic theories in an external magnetic field
Andrea Amoretti, Daniel K. Brattan
In this paper we review recent progress on relativistic hydrodynamics in (2 + 1)-dimensions with an external magnetic field. We discuss the formalism allowing for momentum loss due…
Massless Scalars and Higher-Spin BMS in Any Dimension
Xavier Bekaert, Blagoje Oblak
Starting from the asymptotic kinematics of massless scalar fields near null infinity in any spacetime dimension, we build two higher-spin extensions of the Carrollian definition of…
Celestial holography on Kerr-Schild backgrounds
Riccardo Gonzo, Tristan McLoughlin, Andrea Puhm
We explore the celestial holography proposal for non-trivial asymptotically flat backgrounds including the Coulomb field of a static and spinning point charge, their gravitational…
Black holes in dS
Roberto Emparan, Juan F. Pedraza, Andrew Svesko +2
In three-dimensional de Sitter space classical black holes do not exist, and the Schwarzschild-de Sitter solution instead describes a conical defect with a single cosmological hori…
Revisiting the Carrollian Scalar Field
David Rivera-Betancour, Matthieu Vilatte
We investigate the (conformally coupled) scalar field on a general Carrollian spacetime in arbitrary dimension. The analysis discloses electric and magnetic dynamics. For both, we…
